Engineering Grain Boundary Commensurability for Ferroelectric Stabilization in Hafnia-Based Films
Chuqiao Shi, Xinyan Li, Xing He +11
Grain boundaries fundamentally dictate the macroscopic properties of polycrystalline materials by breaking long-range symmetry. In ferroelectrics, these structural discontinuities…
Direct determination of antiferroelectric-to-ferroelectric phase transition pathways in PbZrO with Operando Electron Microscopy
Menglin Zhu, Michael Xu, Louis Alaerts +5
Under a sufficiently high applied electric field, a non-polar antiferroelectric material, such as \ce{PbZrO3}, can undergo a rapid transformation to a polar ferroelectric phase. Wh…
Operando Electron Microscopy of Nanoscale Electronic Devices on Non-Conductive Substrates
Menglin Zhu, Michael Xu, Zishen Tian +7
Achieving operating conditions comparable to ``bulk'' electronic devices, such as thin film capacitors, during \textit{operando} electron microscopy remains challenging, particular…
Bridging experiment and theory of relaxor ferroelectrics at the atomic scale with multislice electron ptychography
Menglin Zhu, Michael Xu, Yubo Qi +7
Introducing structural and/or chemical heterogeneity into otherwise ordered crystals can dramatically alter material properties. Lead-based relaxor ferroelectrics are a prototypica…
Insights into Chemical and Structural Order at Planar Defects in a Functional Oxide Using Multislice Electron Ptychography
Menglin Zhu, Michael Xu, Yu Yun +7
Switchable order parameters in ferroic materials are essential for functional electronic devices, yet disruptions of the ordering can take the form of planar boundaries or defects…
